DATA CORRECTION DEVICE AND METHOD OF THREE-DIMENSIONAL SENSOR

PROBLEM TO BE SOLVED: To provide a data correction device and method of a three-dimensional sensor capable of correcting automatically a reference plane, when installing the three-dimensional sensor on the ground and detecting and measuring an object on the sea surface, and adjusting automatically a coordinate system of each sensor to a common global coordinate system, when installing each three-dimensional sensor on each different position respectively and using in common a plurality of three-dimensional sensors. SOLUTION: The device includes an acquisition means 22 of a latitude and a longitude, a date-and-time acquisition means 24, a tide level calculation means 26, and a three-dimensional coordinate correction means 28, and the device corrects coordinate data of the three-dimensional sensor 10 by using the tide level calculated by the tide level calculation means 26. The device also includes an azimuth acquisition means 32, and a three-dimensional coordinate reference setting means 34. Since the latitude and the longitude, the azimuth, a height from a level surface, and an inclination amount (pitch roll) from the level surface can be acquired, the device can set automatically a reference of the three-dimensional coordinate of the global coordinate system itself sto agree with the global coordinate system.
